Abstract
Disclosed is an electric machine () comprising a stator () that encompasses a winding system () with three winding branches, and a certain number of effective pole pairs. Each winding branch is provided with at least one coil group, each of which contains an even number of serially connected individual coils () that generate an individual magnetic field, respectively. Two respective individual coils () of a coil group are offset relative to each other in a circumferential direction of the stator () in such a way that the associated individual magnetic fields are provided with an offset electrical angle relative to one another at the sixth harmonic of the number of effective pole pairs, said offset electrical angle being equal to an odd multiple of 180°.
